interface allows you to connect your Gnome amp to a PC, MAC or compatible mobile device to record your playing or to process your signal using
digital audio software plug-ins.
Precautions / Safety Instructions
Power Supply
The Warwick Gnome is powered by an IEC power cable, which provides AC power to the unit. Connect the IEC power cable to provide power.
Improper line voltage can cause serious damage to the unit, always check the line voltage marking on the amplifier before you connect the IEC
power cable. Unplug the unit when not in use or during electrical storms.
Connections
Always turn off power to all other equipment before connecting or disconnecting. This will help to prevent malfunction and damage to any of
the devices used.
Cleaning
Clean only with a soft, dry cloth.

1.
Input Jack: Accepts 6.35 mm (1/4“) audio jacks for connecting active or passive basses. If you use effects pedals, connect the output
from the last unit in the signal chain here. We recommend using high quality instrument cables for best sonic performance and reliable
connection.
1.
Power Switch: This switch turns the Gnome amplifier on and off. Connect the power cord from the mains outlet to the amplifier before
you turn this switch on. To disconnect the amplifier, turn the switch off first, then disconnect the power cord from the outlet and finally
disconnect the power cord from the amp.
2.
Signal LED: The LED will light up green when the instrument signal passes the preamp without any compression. Higher input levels and
gain settings will activate the built-in compressor / limiter to prevent clipping in the pre-amp stage. The LED will light up red to indicate
active compression. The compressor also tracks changes made to the EQ settings, therefore an increase in an EQ setting might require a
decrease in the Gain setting to maintain the same amount of compression.
2.
AC Mains In: This is the power socket for an IEC line cord, which provides AC power to the unit. Always make sure to check the line voltage
marking on the unit before you connect the power cord. Improper line voltage may cause serious damage to the unit.
3.
Speaker Out: Accepts 6.35 mm (1/4“) mono jacks to connect an external speaker cabinet. The minimum load for the amplifier is 4 ohms.
4.
XLR DI Out: Low impedance balanced XLR output for connecting the amplifier to a stage box, mixing desk or the PA for live and studio
use. The XLR DI out is configured post-EQ with standard wiring (Pin 1: Ground, Pin 2: Signal +, Pin 3: Signal -).
5.
Ground Lift: The switch will disconnect the ground connection from pin 1 on the DI output XLR socket. Use this function only when you
face excessive hum, possibly caused by a ground loop. Usually this switch should be left in the out position.
6.
USB Out Port (only on Gnome i and Gnome i Pro): Connect the USB type B port to PC, MAC or compatible mobile devices to use the
audio interface.
3.
Gain: Adjusts the input gain of the pre-amp stage.
4.
3-Band EQ: The active tone control EQ section provides up to +/- 15 dB cut or boost for each band. All controls set to center position
(12 o‘clock) will provide a flat EQ, turning the knobs clockwise will boost the frequency band, turning the controls counterclockwise will
cut the frequency band.
5.
Master: The master volume control sets the signal level for the power output stage and the speaker output on the back of the Gnome
amplifier. Set Master completely counterclockwise before you turn on the amplifier and increase the control slowly until you reach the
desired volume level. A built-in limiter will prevent power amplifier clipping when maximum power is detected.
6.
Power LED: The LED will light up green when the Gnome is powered and turned on.
7.
Headphone Jack: Accepts headphones with 6.35 mm (1/4“) audio jacks. Silent practicing is possible if you disconnect the speaker output
and input your headphones. Silent practicing without connected load will not cause any damage to the amplifier.

6.
Start playing!
Setup a Mac OS X Device
1. Use an USB-B to USB-A cable to connect the amplifier to your computer.
2. Your computer will recognize the interface automatically and set all parameters accordingly. If you have problems with the automatic
setup, go to System Preferences > Sound.
3. Under the Output tab, select USB AUDIO CODEC as your default device.
4. Under the Input tab, select USB AUDIO CODEC as your default device.
5. Close the window.
Protective Circuits
Your new Warwick Gnome amplifier comes with multiple protective circuits to prevent malfunctions under unsuitable operating conditions.
USB Interface (only Gnome i and Gnome i Pro)
Over-Current / Short-Circuit Protection
The Warwick Gnome i and Gnome i Pro amplifiers feature an USB audio interface that can be used as universal connection device for PC, MAC or
compatible mobile devices without any specific drivers or software requirements. The interface uses high quality ADC/DAC converters to convert
your audio signal to be processed with the many applications available or for direct recording in your DAW. Gnome i and Gnome i Pro are
functioning as external soundcards for your mobile device or PC/Mac, converting your instrument‘s signal into a digital audio signal. The interface
section is compatible with any USB device that can manage digital audio signals, via a standard USB-B to USB-A cable.
The amplifier features an over-current / short-circuit protected output. A current drop occurs when the amplifier exceeds the specified peak current
output. This goes along with the drop in the voltage of the amplifier. If the current output of the amplifier exceeds its specified peak current output
for a longer period of time e.g. in case of a short circuit of the output, the amplifier will be disabled (muted) for 1000 ms and automatically restart.
Setup a Windows 7 / 8 / 8.1 / 10 Device
DC Output Protection
A built-in DC protection circuit will attenuate any DC signals on the power amplifier input, produced by a signal containing a DC signal. In case of
a permanent DC on the output of the amplifier, the amplifier will latch and power must be removed for the product to restart.
1. Use an USB-B to USB-A cable to connect the amplifier to your computer.
2. Your computer will recognize the interface automatically and set all parameters accordingly. If you have problems with the automatic
setup, open the sound settings (right-click on the Windows Start button > Control Panel > Sound).
3. Click the Playback tab and select USB AUDIO CODEC as the default device.
4. Click the Recording tab and select USB AUDIO CODEC as the default device.
5. Open Input Properties > Additional Properties.
6. In the new window, click the Advanced tab and select 2-channel, 16-bit, 44100 Hz (CD Quality) as the default format.
7. Uncheck both boxes under Exclusive Mode.
8. Click OK to close the Sound control panel.
Excessive Temperature
This circuit protects the power stage from malfunction by switching the device off if the temperature-regulated fan cooling proves to be insufficient
and temperature of the unit is too high.
